Tom and Jerry pointlessly morph into black characters, strictly to allow haphazard Amos & Andy schtick. Then a bunch of crazy stuff happens, and the cartoon ends with Tom and Jerry being chased by cannibals - the bone-inna-nose kind you don't see in cartoons today. Guaranteed to amuse and offend!
This cartoon is widely available on a DVD compilation of nicely-mastered and apparently restored prints of Tom and Jerry cartoons, which sells for $1 in bargain stores everywhere. Look for it at your local dollar store before eating up your bandwidth with this download. While you're there, you'll probably find the other $1 DVD collections featuring all the Fleischer SUPERMANs, other Van Beuren cartoons, and many more.
